Leon 2.0 TDI CR CUPA — EDC17C64 539136 Bosch — ECU Firmware
This Stage 1 tune is engineered to unlock the full potential of the powerful Seat Leon 2.0 TDI CR with the CUPA engine, controlled by the Bosch EDC17C64 ECU (software 539136). This is more than a simple economy tune; it's a performance calibration designed to enhance the sporty character of this diesel hot-hatch.

Our remap focuses on delivering a substantial increase in torque across the entire powerband, resulting in relentless acceleration and a much more aggressive and responsive driving experience. The tune transforms the car, making it feel significantly faster and more powerful in every gear, perfect for the enthusiast driver who appreciates massive diesel torque combined with hatchback agility.
